BartSMP [9]

Explanation:

Wooho Physics my favorite subject! And my 100th answer :)

We will use the formula

$\boxed{\tt{ Acceleration = \dfrac{v - u}{t}}}$

Where v is Final velocity
And u is Initial velocity.
t is time taken.

In this question :-

u is 4 m/s
v is 6 m/s
t is 5 seconds

Applying the formula:-

$\sf{ Acceleration = \dfrac{6 - 4}{5}}$

$\sf{ Acceleration = \dfrac{2}{5}}$

So, Acceleration is 0.4 m/s² is the answer.

Hope it helps :)

BaLLatris [955]

Answer:

average force is 138900 N

Explanation:

given data

speed = 50 km/h = 13.89 m/s

mass = 1500 kg

time = 0.15 s

to find out

average force

solution

we know initial velocity of car is positive

we will apply here equation to find force that is

Force x change in time that is equal to mass x change in speed ................1

so put here all value of mass, time and velocity in equation 1

Force x 0.15 = 1500 x ( -13.89)

force = 138900 N

so average force is 138900 N
